St.Alphonsus Ligouri said Mohammad is in Hell, like other Muslims. The saints and popes said the same.Vatican Council II also says all need faith and baptism for salvation and all need to enter the Church as through a door(AG 7).Mohammad did not have Catholic faith and neither was he baptized with water.

Being saved with the baptism of water and Catholic faith is the ordinary means of salvation.In general all Muslims need to be visible members of the Church for salvation.

We cannot say that he was saved with the baptism of desire or in invincible ignorance since even if there was such a case , God could send a preacher to baptise the person in ignorance. So every one who enters Heaven is Catholic with Catholic faith and the baptism of water.

Being saved with the baptism of desire etc is a possibility known only to God. There is no such case known to us.Neither can be expect to know, any such case in the present times.

So we cannot meet anyone in the present times who will be saved with the baptism of desire or invincible ignorance. Since the ordinary means of salvation is visible entry into the Catholic Church (with faith and baptism of water) and there are no cases of the baptism of desire etc for us, in 2013.

We cannot say that Mohammad was saved in invincible ignorance since the only means to go to Heaven is the baptism of water given to adults with Catholic Faith.He was also not ignorant of the Catholic Faith.

The Koran shows that Mohammad knew about Jesus and the Church and yet choose not to enter. Vatican Council II (LG 14) says those who know about the Church and its necessity for salvation but do not enter, are oriented to Hell.

Vatican Council II (AG 7) is placed in the Catechism of the Catholic Church under the title outside the church no salvation.

AG 7 is in agreement with the defined dogma extra eclesiam nulla salus based on John 3: 5 and Mark 16:16.

There are no known exceptions mentioned in Vatican Council II to AG 7 or the dogma extra ecclesiam nulla salus.In the present times we do not know anyone saved through good and holy things in their religion (NA2) , seeds of the word , invincible ignorance or a good conscience (LG 16) . So these cases are not exceptions to all needing to convert into the Church through faith and baptism ; all needing to be visible members of the Catholic Church to go to Heaven and avoid Hell(for salvation).

Vatican Council II agrees with the popes and saints in saying Mohammad is in Hell. The official teaching of the Catholic Church,acccording to magisterial documents , before and after Vatican Council II, and including Vatican Council II, have not changed.

The founder of Islam, a religion which has good and holy things in it and politically is one of the 'great religions' like Judaism, was oriented to Hell.

This is a truth of the Catholic Church which still teaches exclusive salvation.Since there are no known cases of Muslims or other non Catholics saved, outside the Church, there is no basis for a theology of religions or a new ecclesiology. Catholic ecclesiology is still ecclesiocentric, based on Vatican Council II (LG 14,AG 7). There is exclusive salvation in only the Catholic Church according to Vatican Council II,which does not mention any exception to the dogma extra ecclesiam nulla salus or to AG 7 (all need faith and baptism for salvation).
